Dell UltraScan P1110 flat-screen monitor BLURRY?

The button you pressed is the reset button and according to the documentaton "returns the monitor to factory defaults".

Here's a link to the Dell support page for your monitor:

Regarding the lines that were orginally were trying to fix; see Damper Wires in Troubleshooting in the above documentation and you'll see that they're a fact of life with this type of monitor. I realize this may not have been your problem, but then again...

I'm surprised that the factory reset made things blurry. Usually this is the result of less than optimum settings on the display adapter in your computer rather than the monitor itself. The Trouble Shooting guide says the brightness and contrast being set too high can cause this so that may be worth checking.

I think you should check your display adapter settings after you try the Troubleshooting suggestions. On the desktop of your computer right click in an empty spot and select Properties. Click on the Settings tab and see what the resolution is. If it's not 1280x1024 you might want to try that. Everything on the screen may suddenly appear smaller so don't be surprised. I would also check the monitor frequency. This will probably be found under Advanced. Every display adapter is different so I can't tell you exactly where to look, just polk around. If you start changing things you may want to write down the original settings so you can at least get back to where you started if there's a problem.

Lastly, I want you to know I'm not paid to provide these suggestions. I know it's a strange hobby, but I like helping when I can. If you find this helpful I hope you'll take a moment and provide a positive rating. About half of the solutions I've posted have never been rated... Thanks and good luck.
